I'm adjusting my UPVC door. The (flag) hinge adjustments were logical and worked easily.
But at the side of the door, there are some knobs (highlighted on the attached) that rise up as part of the multi-point locking mechanism when the door handle is operated. Presumably that's to hold the door closed properly in the latch places.
The knobs have a hexagonal inset to allow adjustment using an Allen key. Google suggests these might be called "Latch Keepers" and the adjustment is for "compression".
I had thought maybe turning the knobs anti-clockwise would push the knobs out and further towards the metal vertical part of the frame so the knobs go deeper (or higher or lower instead?)into the latches. But when I try the adjustmnet, I can't actually see anything happening.
What are these things called and what is supposed to happen when one adjusts them, please.
